We claim: 
     
       1. A 2- (2-alkoxy-6-trifluoromethylpyrimidin-4-yl)oxymethylene!phenylacetic acid of the formula I ##STR11## where the index and the substituents have the following meanings: U is CH or N; V is O or NH;   R is C 1  -C6-alkyl;   R 1  is cyano, halogen, C 1  -C 4  -alkyl, C 1  -C 4  -haloalkyl, C 1  -C 4  -alkoxy, C 1  -C 4  -haloalkoxy or phenyl;   n is 0 or an integer from 1 to 4, where the radicals R 1  may be different if the value of n is greater than 1.   
     
     
       2. The phenylacetic acid of the formula I defined in claim 1, where U is CH and V is O. 
     
     
       3. The phenylacetic acid of the formula I defined in claim 1, where U is N and V is O. 
     
     
       4. The phenylacetic acid of the formula I defined in claim 1, where U is N and V is NH. 
     
     
       5. The phenylacetic acid of the formula I defined in claim 1, where R is methyl, ethyl, or iso-propyl. 
     
     
       6. The phenylacetic acid of the formula I defined in claim 5, where U is CH and V is O. 
     
     
       7. The phenylacetic acid of the formula I defined in claim 5, where U is N and V is O. 
     
     
       8. A composition suitable for controlling animal pests and harmful fungi, which comprises a solid or liquid carrier and a phenylacetic acid of the formula I as defined in claim 1. 
     
     
       9. A method for controlling animal pests and harmful fungi, which comprises treating the pests or harmful fungi or the materials, plants, soil or seed to be protected from them with an effective amount of a phenylacetic acid of the formula I as defined in claim 1. 
     
     
       10. A composition suitable for controlling animal pests and harmful fungi, which comprises a solid or liquid carrier and a phenylacetic acid of the formula I as defined in claim 5. 
     
     
       11. A method for controlling animal pests and harmful fungi, which comprises treating the pests or harmful fungi or the materials, plants, soil or seed to be protected from them with an effective amount of a phenylacetic acid of the formula I as defined in claim 5. 
     
     
       12. A sulfone of the formula IV ##STR12## where the index and the substituents have the following meanings: U is CH or N: V is O or NH:   R a  is C 1  -C 4  -alkyl;   R 1  is cyano, halogen, C 1  -C 4  -alkyl, C 1  -C 4  -haloalkyl, C 1  -C 4  -alkoxy, C 1  -C 4  -haloalkoxy or phenyl:   n is 0 or an integer from 1 to 4, where the radicals R 1  may be different if the value of n is greater than 1.   
     
     
       13. A process for preparing the phenylacetic acid of the formula I defined in claim 1, which comprises reacting a pyrimidin-4-ol of the formula II ##STR13## in an inert solvent in the presence of a base with a benzyl compound of the formula III ##STR14## where X is a nucleophilically replaceable leaving group.
